Sealey SV12 Series Power Tool Battery 12V 4Ah Features: Lithium-ion batteries give an all-round better performance than standard Ni-Cd/Ni-MH cells. Maintains a higher energy density level (generally twice that of a Ni-Cd cell) giving more battery power per gram. Has a flat discharge curve - performing better for longer. No memory effect - these batteries can recover from a deep discharge with no tendency to reduce overall capacity. Suitable for use with the SV12 Series. Technical Details: • Part of the SV12 Series, powered by advanced lithium-ion battery technology delivering more power and optimised tool runtime for superior all-around performance. • Lithium-ion batteries give an all-round better performance than standard Ni-Cd/Ni-MH cells. • Maintains a higher energy density level (generally twice that of a Ni-Cd cell) giving more battery power per gram. • Has a flat discharge curve - performing better for longer. • No memory effect - these batteries can recover from a deep
